Recently, a procedure has been established for the determination of the maximally accumulated oxygen deficit (MAOD) (Medbo et al., J. Appl. Physiol. 64:50-60, 1988) as an indicator of anaerobic capacity. We hypothesized that, if MAOD were a valid indicator of anaerobic capacity, it should distinguish between aerobically and anaerobically trained athletes… (More)

OBJECTIVE
We studied whether the quantity and quality of walking necessary to decrease the risk of cardiovascular disease among women differed substantially from that required to improve cardiorespiratory fitness.
DESIGN
A randomized, controlled, dose-response clinical trial with a follow-up of 24 weeks.
SETTING
A private, nonprofit biomedical research… (More)

Bioenergetic interpretations of energy transfer specify that rapid anaerobic, substrate-level adenosine triphosphate (ATP) turnover with lactate production is not appropriately represented by an oxygen uptake measurement. Two types of weight training, 60% of 1 repetition maximum (1RM) with repetitions to exhaustion and 80% of 1RM with limited repetitions,… (More)

Due to current technical difficulties and changing cellular conditions, the measurement of anaerobic and recovery energy expenditure remains elusive. During rest and low-intensity steady-state exercise, indirect calorimetric measurements successfully represent energy expenditure. The same steady-state O2 uptake methods are often used to describe the O2… (More)

As opposed to steady state aerobic-type exercise involving long duration, continuous, rhythmic, large muscle group activities that consume large volumes of oxygen, a resistance training set is brief, intermittent, uses multiple and isolated muscles, and is considered anaerobic in description. Because differences are evident between aerobic- and… (More)

Although aerobic exercise training and diet-induced weight loss each have been shown to individually lower elevated blood pressure (BP), it is currently not known whether their combined use produces an additive antihypertensive effect. In this randomized clinical trial we therefore compared the effect on resting BP of exercise training only and dietary… (More)

There currently is inconsistent information regarding the role that musculoskeletal strength (one component of musculoskeletal fitness) may have in lipid and lipoprotein metabolism, and consequently the risk of cardiovascular disease. Results of existing studies have been conflicting and have been influenced by several weaknesses. We provide cross-sectional… (More)

Over the past 30 years, mortality rates from coronary artery disease (CAD) have decreased by more than 30% in the United States. However, CAD remains the major public health problem in this country. There is now substantial evidence linking exercise training to a reduced risk for CAD and for mortality after myocardial infarction. The actual mechanism by… (More)
